Redis setup help - HTTP/1.1 400 Bad Request

Hello,

I setup a few wordpress sites with --wpredis. I have the nginx helper and redis plugins installed and setup and they seem to talk to the redis server.

However, when I go to any of the sites with: curl -X get -I https://sitetocheck.net/

I get:

HTTP/1.1 400 Bad Request Server: nginx Date: Mon, 08 May 2017 14:17:22 GMT Content-Type: text/html Content-Length: 166 Connection: close

I’m expecting to see: X-SRCache-Fetch-Status: HIT

The Bad Request, I’m assuming is when it should be passing off to redis?

Could anyone provide some guidance with this please, thanks! In particular, I’d like to be certain redis is working because based on page load speeds, I’m pretty certain it isn’t.

-Chad.
